摘要：

1,1-Dibromo- and 1,1-dichlorocyclopropanes are converted into the corresponding monohalo-cyclopropanes (as mixtures of stereoisomers where appropriate) by reaction with 1.2-1.3 mol. equiv. of ethyl magnesium bromide and a snell amount of titanium isopropoxide in ether. In the presence of an excess of ethylmagnesium bromide the product from the dibromide is the non- halogenated cyclopropane. Copyright (C) 1996 Elsevier Science Ltd
